Sin A / CB Sin C/ AB Sin A/25 Sin 108/ 38 Sin A = sin -1 (25sin(108)/38) Sin A = 38.7
 * 1) 18) in the triangle ABC, m< c= 108, CB = 25 and AB= 38, I need to find the remaining sides and angles in the triangle.

Find the measure of <B m<B = 180 - (108+38.7) m<B =33.3

find AC Sin B/ AC Sin A/ BC Sin 33.3 / AC Sin 38.7/25 AC=( 25 sin(33.3)/sin(38.7)) AC= 21.9

 * Similar Triangles** are triangles that share the exact degree of angles.



The smaller triangle is similar to the bigger triangle. You'll be able to solve for **z** because they are similar. To solve for **z**, you would have to write it as an equations or a proportion.

There are only two ‘special' right triangles. Angle based and side based.


 * Sophia Moreno**

o False
 * 18.** There are only two ‘special’ right triangles.

There are three: 3-4-5 triangles 45°-45°-90° triangles 30°-60°-90° triangles

o True
 * 19.** The ‘special’ right triangles can be used to verify the trigonometric identities.

John Derry and Charles Williams 18. There are only "special' right triangles. **True** Special Right Triangles There are 2 kinds of special triangles. The 2 kinds of special right triangles are angled based and side based. The angle based special right triangles are: 30-60-90˚ 45-45-90˚ The side based special right triangles are: The Pythagorean Triples Such as: 3-4-5 The Fibonacci Triangle and The almost-isosceles Pythagorean Triples


 * Kimberly Bush**

18: False -Isosceles -Scalene -Equilateral

19: True -Triangles are used when using sine, cosine, and tangent

Lenea Harris: Special Right Triangles

1. There are only Two ‘Special” Right Triangles. True False

Answer: True

Examples: There is the side based special triangles and the angle based special triangles.

The side- based triangles are the 45°- 45°- 90° and the 30°- 60°- 90°

One angle based is the 3- 4- 5

=Fx-39 (a + b)= Problem: A Solve for x. Answers: 32 18
 * a:** __18__ = __x__

__324 = 32x__ 32


 * 10.125 = x**

Problem: B

Solve for x. 10 15 - x
 * b:** __17__ = __15__

17(15 - x) = 150

255-17x=150 -255

__-17x = -105__ -17


 * 6.18 = x**
